I will like to configure my Router to access ISP directly, and I will like to take these tasks step by step as you better outlined them.

Currently the router interface facing the modem is getting Private IP address (precisely from the DHCP service running in ISP provided modem). The IP its getting is 192.168.1.8
(is a DHCP client), while the interface interfacing the LAN is static IP address.
Based on these, can anyone guide me on how to configure the ISP provided username, password, NAT, Protocols, etc on the router, together with these information:

ISP:
ISP's username - sksk123 (sksk123@myisp.com)
ISP's password - password123
ISP's domain - myisp.com
ISP's pop3 - pop3.myisp.com
ISP's smtp - smtp.myisp.com
ISPs smtp port - 555

Router:
Internal interface (ether0) - 192.168.11.1
External interface (serial0) - 192.168.13.1

By the way the connection line to the isp is fibre optics.
And I receive DHCP assigned IP address from the ISP, not static.

1, So, how do I configure things up?
2, Will the Serial0 interface be configured as a DHCP client? (I'm assuming so)
3, As NAT will be configured in the both interfaces, if Serial0 interface will be configured as DHCP client, how then do we configure NAT in it?

Thanks

Model numbers of the router and Modem you are using would be useful, in fact essential if you are ever likely to get an answer to your question.
Unless the router has a built in Modem you cannot connect directly to your ISP and you are going to need the Modem

This is cisco 2600 router.
By the way, the intention is not to connect the router directly to the ISP, but to have it just behind the ISP provided modem.
The modem will act as modem but the actuall PPoE connection will initialize from the router.
i.e:
The ISP line <-> Modem <-> Router <-> LAN

PPPoE is a function of the Modem, not a router.
It stands for Point to Point Protocol over Ethernet. It is the protocol that you Modem uses to communicate with your ISPs Modem. The Input and Output from a Modem is pure Ethernet. It establishes a Point to Point link between you and your ISP.
SMTP and POP3 are configured in you mail client and have little to with router or Modem. All you need to do is to ensure the necessary ports are open and your mail client will do that unless you are running a mail server.

ourmember your posted ip isn't correct.
Internal interface (ether0) - 192.168.11.1
External interface (serial0) - 192.168.13.1
but you have "The IP its getting is 192.168.1.8 "
Presently with your pc connected to the modem and using the software the isp provided, when you enter your user name and password do you get connected to the internet?
If so post the results of an ipconfig /all for review.
Sorry but I don't believe that is correct concerning modem and pppoe
http://www.dslreports.com/faq/10952
There are lots of other examples of routers without builtin modem getting setup for pppoe authenication. The pppoe authenciation is usually done via installed sofware on the subscribers pc. PPPoE routers just put that authenication on the wan interface of the router.
Answers are only as good as the information you provide.
